Title: Gas meter
Inventor: TANAKA YUTAKA
IPC: G01F1/66
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To improve a measurement accuracy by obtaining a sound velocity and a flow velocity in a gas flow from a time inverse number difference and a time inverse number sum of ultrasonic wave reach times in a forward direction and a backward direction between a set of ultrasonic transmitters/receivers set at a constant distance in the upper stream and lower stream of a streamtube, specifying a gas type from the sound velocity, multiplying the flow velocity by a constant corresponding to the gas type and correcting the flow velocity. SOLUTION: A set of ultrasonic transmitters/receivers 1 and 2 are set at a distance L in the upper stream and lower stream of a streamtube 3. A reach time t1 in a forward direction and a reach time t2 in a backward direction of ultrasonic waves between the two transmitters/receivers 1 and 2 are obtained, and a sound velocity C is obtained from a time inverse number sum F of the reach times t1 and t2 according to F=(1/t1)+(1/t2)=2C/L. Then, the sound velocity C is compared with a table of a memory set in a gas type judgment means and a type of the gas is judged. A flow velocity V of the gas is obtained from a time inverse number difference (frequency difference) Δf of the reach times t1 and t2 according to Δf=(1/t1)-(1/t2)=2V/L.  The flow velocity V is corrected with the use of a correction expression of multiplying a constant corresponding to the gas type, and a corrected flow velocity V' is obtained.

Abstract: PURPOSE:To maintain control balance and improve operability by referring to a correction map to correct a target value based on the temperature at the time of starting air conditioning and a passage period of air conditioning control when a hot/cold-sensitive switch is operated. CONSTITUTION:The signals of respective sensors 42-44 of an outside temperature, an inside temperature, and the quantity of sun radiation are inputted into a control unit 12 to compute an equivalent temperature, and a total computation value is computed from the equivalent temperature and a target temperature. From respective control signals based on the computation value, an intake door 15, an air blower 16, a compressor 25, a mix door 18 and mode doors 24a-24c are controlled respectively.

Title: Sheet roll shaft
Inventor: KATAOKA AKIRA
IPC: B65H18/04
Filed: 1986-07-02
Abstract: PURPOSE:To aim at simplification in maintenance work, by installing a shaft body having an outer diameter capable of externally inserting a core and plural elastic engaging members, capable of engaging an inner circumferential surface of the sais core and being installed in the said shaft body circumference radially outward along the axial direction. CONSTITUTION:Since plural engaging members 6 having elasticity each are installed in the circumference of a shaft body to be situated in height capable of engaging an inner circumferential surface of a core C radially outward along the axis, when the core C having an axial projecting part 7 is externally inserted into the inner circumference, they are depressed as giving common pressing force to the inner circumferential surface of the core C. Therefore, the shaft body and the core C come into an almost concentric state. And, one in these engaging members 6 is engaged with the side of the projecting part 7 as giving pressing force to the core inner circumferential surface when the shaft body is rotated and driven, whereby it rotates and drives the core C in the same direction as the shaft body. In this case, other engaging members 6 give the specified pressing force to the inner circumferential surface of the core C. When the shaft body is rotated in the reverse direction to the above- mentioned, the core C and the shaft body both are rotated in the same direction.
